AfterCommercial Solar Installation in Georgetown, TX: What It Costs and How GUS Interconnection Works
A commercial solar installation in Georgetown typically runs $2.10 to $2.85 per watt before incentives, which puts a 100 kW rooftop system between $210,000 and $285,000. The payback period here is different from neighboring Round Rock or Cedar Park because Georgetown Utility Systems (GUS) sets its own net-metering buyback rates through City Council, not the ERCOT retail market. Before any panel goes on a roof, your project has to clear GUS’s municipal interconnection process. That single fact shapes every commercial quote we write in this city.
Call (877) 550-6892 and we’ll walk your actual utility bill through the GUS tariff math. No pressure, no signature tonight. Bring me a bill, I’ll bring you the math.
Why Gus’s Solar Is Georgetown’s Preferred Commercial Solar Installation Company
Gus Petrakis founded this company in 2011 and put his own name on the truck. We’re not a door-knocking crew that rolls through Williamson County for a season and moves on. Gus lives here, answers the phone here, and if something goes wrong with your commercial array, he’s the one who comes back. That’s the 90-Day Done Right Promise in writing on every job. One call brings Gus back.
Georgetown business owners have been burned by national outfits that quote one number on the phone and another at the signing table. We hear it constantly. Our price is the price. Our crew does the install, not a sub. Background-checked, uniformed technicians, and a live person answers 24/7. Not a voicemail tree. Not a portal. A person.
We know the Georgetown Utility Systems process inside out because we file these applications every week. When a commercial project stalls, it’s almost always because an out-of-market installer filed the wrong paperwork with the wrong utility. We don’t make that mistake. That’s why our Commercial Solar Installation team handles everything from the GUS application to the final inspection without you chasing paperwork.
Our L.O.C.A.L. values aren’t a marketing slogan. Local roots, On time, Community first, Accountable, Loyal. In Georgetown, that means showing up when we say we will, quoting real numbers off your actual electric bill, and being at the hardware store where you can find us if you have a question. Take two weeks after our quote. Think about it. The price will be the same.
Our Commercial Solar Installation Services in Georgetown
Commercial Rooftop Solar
Rooftop arrays make up most of our commercial work in Georgetown, particularly in the Wolf Ranch and Teravista commercial districts along I-35 and Williams Drive. These buildings have large, flat or low-slope membrane roofs that take ballasted racking well. We quote the year-25 output, not the day-one brochure number. If a roof slope faces north because of HOA sight-line rules near Sun City, we run the production model before you sign anything and show you the real number. A 100 kW system on a south-facing Georgetown rooftop produces differently than one on a compliant north slope, and you should know that number before you commit.
Commercial Battery Storage
Georgetown businesses are asking about battery storage more every year, and for good reason. Summer cooling loads in Williamson County spike demand charges. A FranklinWH or Tesla Powerpack system sized to your building’s load profile can shave those peaks and shift grid draw off GUS’s high-rate afternoon window. We pair FranklinWH and Tesla systems with Enphase or SolarEdge inverters depending on your roof layout and GUS’s line-side tap requirements. Commercial storage also gives you backup when a spring supercell takes out a feeder line, which happens more often than people like to admit in the 78626 and 78628 ZIP codes.
Warehouse & Industrial Solar
Distribution centers and light industrial buildings along the I-35 corridor between Georgetown and Round Rock are some of the best solar candidates in the county. They have big flat roofs, minimal tree shading, and high daytime loads. We recently wrapped a 180 kW rooftop array on a warehouse off Williams Drive in the Wolf Ranch commercial district. The owner had two quotes from out-of-market installers who never pulled the GUS interconnection checklist. Their production estimates assumed Oncor net-metering rates. Wrong utility, wrong math. We used REC panels with Enphase microinverters, added rapid shutdown to meet GUS’s line-side tap rules, and walked the application through GUS.
Solar Carport Installation
Carports solve a problem many Georgetown commercial properties face: roof space that’s too small, too shaded, or too old to carry a solar array. We see this in the historic downtown core around the Williamson County Courthouse, where lot lines are tight and roofs are older. A solar carport over employee or customer parking gives you generation plus shade, and it doesn’t touch the building envelope. Class 4 hail-rated panels are standard on our Georgetown carports. In this hail corridor, anything less is a future warranty fight.

Trusted Brands We Service in Georgetown
We install and service equipment from Tesla, Enphase, SolarEdge, and FranklinWH.

If your existing commercial array was installed by someone else and it’s underperforming, we’ll come out, diagnose it, and tell you honestly whether it’s worth fixing. If a salesman needs an answer tonight, the answer is no. We don’t work that way, and you shouldn’t either.
Common Commercial Solar Installation Problems We See in Georgetown
- Wrong interconnection paperwork. A commercial contractor files with Oncor or plugs into the ERCOT portal instead of GUS’s municipal application. The project sits in limbo for months. We’ve rescued several Georgetown jobs from this exact stall. Pulling the GUS checklist before the first site visit avoids it entirely.
- Cheap, non-hail-rated panels. Georgetown sits squarely in the I-35 hail corridor. Golf-ball-sized hail hits Williamson County every few springs. A standard 25mm impact panel with a Class 1 or 2 rating will crack, and the manufacturer will deny the warranty. We spec IEC 61215 Class 4 impact-rated modules on every commercial roof in Georgetown. It’s not an upsell. It’s the minimum.
- North-facing roof planes without production modeling. Commercial pads near Sun City Georgetown and some Wolf Ranch tracts have deed restrictions limiting panel visibility from main roads. Thousands of homes and commercial buildings in Sun City have north-facing front elevations. If an installer doesn’t run a production model before signing, the array can underproduce by 15-20% annually compared to a south-facing system. You deserve the year-25 number before you commit, not an apology after.
- Ballasted racking on aging TPO roofs. We see commercial roofs in Georgetown that are 15-20 years old, with degraded membrane and failed seams. Putting ballasted solar on top of that roof means a re-roof in five years requires full panel removal and reinstallation, doubling your cost. We inspect the roof surface and tell you plainly if it should be replaced first. We’d rather lose a solar sale than sell a system onto a roof that won’t carry it.

FAQs - Commercial Solar Installation in Georgetown
GUS sets its own buyback rate by City Council action, not the ERCOT retail market. Neighboring Round Rock and most of Williamson County fall under Oncor’s delivery area with retail provider credits, but Georgetown’s municipal utility pays a different rate for your excess generation. That changes your payback math meaningfully. The same commercial rooftop in Georgetown and Round Rock can have payback periods that differ by two to three years. Call (877) 550-6892 and we’ll run your GUS bill through the actual tariff.
Yes, commercial rooftops in Georgetown need Class 4 impact-rated panels. This stretch of I-35 gets golf-ball hail with spring supercells about every three to five years. Installers who skip hail-rated modules see cracked glass and denied warranty claims after the first bad storm. We spec IEC 61215 Class 4 as standard, not as a line item.
Expect roughly 15-20% less annual output than a south-facing array of the same size. This is common around Sun City Georgetown and some Wolf Ranch commercial pads where HOA sight-line rules push panels to north-facing slopes. We run a production model before you sign anything so you see the year-25 number on the roof you actually have, not the roof a brochure assumes.
Yes. GUS requires rapid shutdown capability and a utility-accessible disconnect on commercial systems, and the specifics differ from what Oncor requires in neighboring cities. We build these requirements into every Georgetown quote from day one. Filing the GUS interconnection application correctly with the right equipment listed avoids months of delay. Call us and we’ll walk you through the checklist.
With GUS, a clean application typically clears in three to six weeks because you’re working through a single municipal point of contact. Interconnections in Oncor territory often take two to three months. The catch is that a wrong or incomplete GUS application stalls fast, which is what happens when out-of-market installers file ERCOT or Oncor forms. We just pushed a 180 kW warehouse interconnection through GUS in three weeks using the correct checklist.
